Anti Virus Software

[airbirduk]

So my Mum curerntly has AVG free version loaded on her computer as her anti virus. She goes away on vacation for up to 7 weeks at a time. When she comes back she tries to update AVG but because she still uses a phone line for her internet connection the update takes days!!!

Therefore is Norton the best route to go down to avoid this huge update issue? Or is there a better way, apart from telling her to get broadband.

Thanks.
